Right at this point, it would be in your partners benefit to be married with regards to his 'rights' towards your child. If you are married he will automatically go on the birth cert.
As long as we register the birth together, DP gets parental responsibility same as I do. And actually, if we're not married we can each indicate a guardian to act if we die, what if you don't get to register together??
If one of you did die you will have to pay more inheritance tax and companies may refuse to deal with the surviving partner in favour of 'legal' next of kin ie: at this point, the law will see next of kin as your/his parent.
You say you own business together, so if one of you decided to be a stay at home parent, you possibly have less risk that relying on a single salary and in the chance you were to break up the SAHP would still have an income.
Plus, my understanding is that it's not cut-and-dried who makes decisions for the unconscious in hospital and I'm not sure that's a likely enough scenario to be worth making a major life decision on.
Its more cut and dried that you think. Hospitals are very wary of legal battles now. And it's not just death what if one of you was to become incapacitated?
Do you have each others 'lasting power of attorney'? (www.gov.uk/power-of-attorney/overview)
Wills won't/don't cover you for that.
A hospital will go with the legal NOK in emergency situations.
The thing is it isn't just about what will happen if you split up, what will happen, if one of you die? It happens young, healthy, fit, about to become parents all the time.
What will happen if one of you sustains a brain injury? Or an accident where you need to decide whether to continue care or not?
I know everyone would like to believe that their family would do the right thing but trust me as an ex nurse I've seen the best and the worst in people.
People who still believe in common law marriage and ending up homeless.
Parents deciding they never really liked the long term partner of their child and banning them from their bedside.
Adult children banning long term partners and making them homeless.
Legal NOK making decisions about care that the partners knows the patient would not want.
Men & Women who'd helped raise their partners children for years suddenly been banned from their lives. (yes I know marrying their parent doesn't give automatic rights, but it does help prove an ongoing relationship if taken to court).
People left with no access to funds to fight court cases to uphold wills etc
As well as seeing this in work, we had to deal with it all when OH's sister was killed in an RTA.
She'd been with her partner 10+ years.
No company would deal with him it all had to go through OH as her legal NOK. Admittedly she didn't have a will, but we asked if this would have made a difference and told no, he would have still had to apply for grant of representation.
On the one hand we got to take some of the burden off him, on the other he still feels 'guilty' that he didn't get to do it even though we involved him in all aspects.
These are all scary horrible things to have to think about but you have to, not only to protect you, your partner and your child.
So yes marriage is a hangover still of when women were chattel to passed over on their fathers say so, but at this point in time legally it is the best protection for both of you.
